It returns TRUE if mipmap generation succeeds, otherwise it returns FALSE. Mipmap generation may fail when it is not supported for particular texture types or formats. + +Device resets +^^^^^^^^^^^^^ + +The state tracker can query or request notifications of when the GPU +is reset for whatever reason (application error, driver error). When +a GPU reset happens, the context becomes unusable and all related state +should be considered lost and undefined. Despite that, context +notifications are single-shot, i.e. subsequent calls to +``get_device_reset_status`` will return PIPE_NO_RESET. + +* ``get_device_reset_status`` queries whether a device reset has happened + since the last call or since the last notification by callback. +* ``set_device_reset_callback`` sets a callback which will be called when + a device reset is detected. The callback is only called synchronously. |
